Different from any manual line drawing or printing work, it is not workable at all to rely on any manual labor force input. On consideration of high work efficiency and high precision line projection onto different working surfaces, it is just the best job for users to operate a high brightness device of a 532nm green line laser module. The advanced use of a qualified glass coated lens and thermal emitting system are configured with ultra compact and durable metal housing tube. In practical precise line measuring work, this laser line generator just brings users easy reaching, good direction and high precision line generation onto different working surfaces constantly. Unlike the formal use of a green laser pointer, in order to make use of long lasting line projection onto different working surfaces, this 532nm green line laser module is applying even better thermal emitting design. The advanced use of a metal heat sink cooling system is configured with different dimension anodized aluminum alloy housing tube. When it gets freely selected output power of 5mW to 100mW, this laser line generator adopts different size tube diameter of 16mm and 26mm. it just enables easy carrying, good direction and highly stable green line projection onto various working surfaces. From the very beginning design of a 532nm green line laser module, it has been made with a qualified glass coated lens within wide fan angles of 10 to 110 degree. It is applicable for multiple raw material processing works. Different from any formal plastic coated lens, even though line alignment work is processing at long distance or long time, it still gets no effect by laser light decay or dim in proper use. This laser line generator achieves different line lengths within 0.5 meter to 6 meters. According to basic measurement and experiment of technical data, after correct use of output power and optic lens fan angle, it brings users quite satisfied line positioning results for laser cutting, saw mill, lumber machine, textile garment processing and high tech work etc. Being made with APC, ACC driving circuit board, whatever output power it is selecting, this 532nm green line laser module is getting the best performance in long lasting use. It gets reduced possibility of tube burning out or damage, and long serving lifetime of more than 8,000 hours. Under operation that green alignment laser makes freely adjusted laser line fineness and line emitting direction, it achieves highly concentrated green laser light emission, and increasing accuracy line projection at greater distance. When users are taking laser safety issue and wearing proper laser safety glasses, unless it is pointing under sunlight, it just makes easy and secured line positioning results effectively.
